Mapping CCUS Technological Trajectories and Business Models: The Case of CO2 -Dissolved

International audienceAccording to the different climate change roadmaps (IEA, IPCC), Carbon Capture Storage (CCS) will play a key role in the climate change mitigation policy. Its development raises a trade-off between the deployment of large-scale projects (learning by replication), and the preservation of a large portfolio of competing technologies (learning by diversity), on each of its steps (capture, transport, storage). By now large-scale CCS projects are still few, most devoted to EOR (Enhanced Oil Recovery). Although EOR has provided a first feasible business model for CCS, CCS has still to prove its economic viability on a large variety of carbon emitters (power plant, industrial and bioenergy sources). A competing business model for CCS is to find other carbon uses and energy sources, better adapted to medium and small carbon sources. The paper presents such a technological solution, the CO2 DISSOLVED project, which combines CCS in a dissolved state with geothermal energy

Technical and economic feasibility of the capture and geological storage of CO2 from a bio-fuel distillery: CPER Artenay project

AbstractThis paper first focuses on the environmental benefits of the CCS system applied to a bio-ethanol distillery before estimating its feasibility under geological and economic constraints.First, the calculation of CO2 balance in this application shows that the introduction of CO2 capture and sto rage in biomass energy systems (B-CCS) can si gnificantly increase the CO2 abat ement potential of the system and even leads to negative carbon emissions. Besides, a preliminary geological investigation reveals that the studied area has a good storage potential although the presence of major faults, while the low capture costs of CO2 from biomass fermentation emphasize the economic potential o f such a solution

From geology to economics: Technico-economic feasibility of a biofuel-CCS system

AbstractThis paper presents a method to estimate the technical and economic feasibility of capturing and geologically storing CO2 resulting from biomass fermentation. The methodology is applied to the case of bio-refineries in the Paris Basin, France. The first step is to build a 3D geological model of the area studied and to choose the optimal injection location from geological and environmental constraints. Then, based on this information, the design of the CCS system (pipeline length, number and type of wellbores, surface equipment …) and the estimation of the technical feasibility (sufficient storage capacity, risk analysis and management …) can be performed. The last step is the estimation of the environmental benefits of this system (through a carbon and energy footprint) and its economic long term feasibility thanks to a discounted cash flow analysis. The impact of geological constraints on the economic feasibility of the system is estimated through a sensitivity assessment on the number of required injection wellbores
